Can you solve this fiendishly difficult maths question?

1 + 1 = 2

STUDENTS IN THE UK were so mad about this GSCE maths question that they started a petition over it.

It’s all about a girl called Hannah, and her bag of sweets.

Can you solve it?

There are n sweets in a bag. Six of the sweets are orange. The rest of the sweets are yellow. Hannah takes a random sweet from the bag. She eats the sweet. Hannah then takes at random another sweet from the bag. She eats the sweet. The probability that Hannah eats two orange sweets is 1/3. Show that n²-n-90=0.

Head to The Guardian for the solution.
